Because inflation may increase in case of printing money. It may also influence exchange rates as this money was not "earned" and it was not secured, but it was just "printed".

Not possible.

Various theories of Economics and Public Finance need to be followed.

There is a limit to how far you can print money without causing hyper-inflation. There are lots of similar experience from history starting with France in the early 18th century.

Since money would be easier to come by without a simultaneous production in the economy, there would be too much money leading to hyperinflation. The economy could recess further which would further increase debts instead of reducing it

Olatunji A Shobande, I greet for posting this interesting but huge quiz. I do not know where you were during the regime of Idi Amin of Uganda (around 1970 or 1980s) and we were told (not authoritatively confirmed) that President Idi Amin will summon the Governor of the country's Central Bank and orders him to bring some money to him (Idi Amin). And when the Central Bank Governor tells his President that there is no money in the Treasury; that President will instruct him to print more currency notes. During the Nigerian civil war (and my lifetime) my own parents was very rich and in possession of the Biafran currency notes but one thing was common and simple - I doubt whether the Biafran currency had any exchange value to other currencies. Simply put, any country can put into circulation as much quantities of its domestic currencies as possible; but how it translates to purchasing powers of the same currency and exchange to other national/international currencies as well as the nation's foreign reserves matter.

Looking at the characteristics of money, one of them is scarcity. Printing money is not a solution for debt and if money is printed it will not have any value again. Debt is common not only in developing countries but also in developed countries. The presence of debt does not means lack of money because it has to be reimbourse. So relating debt with printing of money is not possible because money will lose its value and its characteristics that make it to serve as a medium of exchange.

They are not free in printing its regulated my IMF

Printing of money more than necessary causes inflation in the economy and hence devalue the country’s currency against other currencies. In effect, the value of the printed money to settle the debt will be offset by the devaluation of the currency.
